Question

alguem me ajuda esqueci como fazer :(
preciso pro trabalho agora !

Answer 1

e) $\dfrac{x}{2} +1= \dfrac{1}{4}$

$\dfrac{2x}{4} + \dfrac{4}{4} = \dfrac{1}{4}$

$2x + 4= 1$

$2x = 1- 4$

$2x = -3$

$x=- \dfrac{3}{2}$

e) $\dfrac{2x}{3} + \dfrac{1}{4} =4x- \dfrac{1}{2}$

$\dfrac{8x}{12} + \dfrac{3}{12} = \dfrac{48x}{12} - \dfrac{6}{12}$

$8x + 3 = 48x- 6$

$8x -48x = - 6- 3$

$-40x = -9$

$x= \dfrac{-9}{-40}$

$x= \dfrac{9}{40}$

g) $\dfrac{x+1}{2} = \dfrac{1}{3}$

$3.(x+1)=2.1$

$3x+3=2$

$3x=2-3$

$3x=-1$

$x= -\dfrac{1}{3}$
